Abstract
A method for enabling a base station to transmit control information in a wireless communication system according to one embodiment of the present invention, comprises a step of transmitting an enhanced physical downlink channel (E-PDCCH) for a terminal using at least one physical resource block pair among a plurality of physical resource block pairs for transmitting the E-PDCCH, wherein the plurality of physical resource block pairs include one or more physical resource block pair sets, and a parameter related to a demodulation reference signal for the E-PDCCH is set with respect to each physical resource block pair set.

1-12. (canceled)
A method for receiving a downlink control signal by User Equipment (UE) in wireless communication that includes a Base Station (BS), the method comprising:
- receiving, by the UE from the BS, information related to an initial value of a DMRS scrambling sequence for each of plural PDCCH resources;
- based on the received information, receiving, by the UE from the eNB, a first PDCCH and a first DMRS via one of the plural PDCCH resources, the first DMRS based on an initial value of a first specific DMRS scrambling sequence for the one of the plural PDCCH resources.
A User Equipment (UE) for receiving a downlink control signal by in wireless communication that includes a Base Station (BS), the UE comprising:
- a memory;
- a transceiver;
- and
- a processor operatively connected to the memory and the transceiver, the processor configured for:
- receiving, from the BS, information related to an initial value of a DMRS scrambling sequence for each of plural PDCCH resources;
- based on the received information, receiving, from the eNB, a first PDCCH and a first DMRS via one of the plural PDCCH resources, the first PDCCH including the first DMRS based on an initial value of a first specific DMRS scrambling sequence for the one of the plural PDCCH resources.
The UE of claim 22, wherein the processor is further configured for, based on the received information, receiving, from the eNB, a second PDCCH and a second DMRS via another of the plural PDCCH resources, the second DMRS based on an initial value of a second specific DMRS scrambling sequence for the another of the plural PDCCH resources.
The UE of claim 23, wherein the first and second PDCCHs are received sequentially
The UE of claim 23, wherein the first and second PDCCHs are received simultaneously
A method for transmitting a downlink control signal by a Base Station (BS) in wireless communication that includes User Equipment (UE), the method comprising:
- transmitting, to the UE by the BS, information related to an initial value of a DMRS scrambling sequence for each of plural PDCCH resources;
- based on the received information, transmitting, to the UE by the eNB, a first PDCCH via one of the plural PDCCH resources, the first PDCCH including a first DMRS that is scrambled with a first specific DMRS scrambling sequence.
A Base Station (BS) for transmitting a downlink control signal by in wireless communication that includes a User Equipment (UE), the UE comprising:
- a memory;
- a transceiver;
- and
- a processor operatively connected to the memory and the transceiver, the processor configured for:
- transmitting, to the UE, information related to an initial value of a DMRS scrambling sequence for each of plural PDCCH resources;
- based on the transmitted information, transmitting, to the UE, a first PDCCH and a first DMRS via one of the plural PDCCH resources, the first DMRS based on an initial value of a first specific DMRS scrambling sequence for the one of the plural PDCCH resources.
